OPNsense automatic updates are relatively conservative.

There was an open hardware project for SD card emulation, where the emulator could reject writes, https://github.com/racklet/meeting-notes/blob/main/community...

Some USB drives (Kanguru) and SSD enclosures (ElecGear M.2 2230 NVME) have firmware and physical switch to block writes, useful to boot custom "live ISOs" that run from RAM.
A read-only partition can bootstrap recovery from cloud, if the main firmware or config is damaged.
Some updates are possible with live kernel patching of the memory-resident OS, which can also be used by malware.
Some motherboards offer a physical jumper for firmware updates, including x86 PC Engines APU2 coreboot router.

> Unified Write Filter (UWF) is an optional Windows 10 feature that helps to protect your drives by intercepting and redirecting any writes to the drive (app installations, settings changes, saved data) to a virtual overlay. The virtual overlay is a temporary location that is cleared during a reboot or when a guest user logs off.. Increases security and reliability where new apps aren't frequently added. Can be used to reduce wear on solid-state drives and other write-sensitive media. Optimizing Application load timing on boot – it can be faster to resume from a HORM file on every boot rather than reloading the system on each boot. UWF replaces the Windows 7 Enhanced Write Filter (EWF) and the File Based Write Filter (FBWF).
The behavior being described sounds a bit like malware. If it happens again, the best option is to Force Restart (VolUp, VolDown, hold side button until the device reboots), which cannot be intercepted by any apps which might be trying to simulate iOS system prompts.
Never heard of this behavior, but it's not associated with the Apple feature called "Lockdown Mode", which does not constrain use of secure enclaves for Touch ID or Face ID authentication, https://support.apple.com/en-us/105120
iOS Lockdown Mode does not usually constrain the method of unlocking the phone.
There's an option during reset to keep the eSIM, https://allthings.how/how-to-factory-reset-iphone-without-er...
Source: purchased devices until finding one that worked, since Apple docs indicated the feature should work on all iPhones that can run iOS 17.
Edit: audio descriptions in Magnifier are non-functional on iPad Air, working on M2 iPad Pro.
Hopefully accessibility features are never artificially segmented to higher priced devices.
Even on Pro devices, audio image descriptions stop working after a few cycles of switching between Image Magnifier and apps/home. This can be fixed by restarting the app and disabling/enabling audio image descriptions, but that breaks the use case when an iPhone is dedicated to running only Image Magnifier + audio descriptions, via remote MDM with no way for the local blind user to restart the app.
On-device iOS image descriptions could be improved if the user could help train the local image recognition by annotating photos or videos with text descriptions. For a blind person, this would enable locally-specific audio descriptions like "bedroom door", "kitchen fridge" or specific food dishes.
Are there other iOS or Android AR apps which offer audio descriptions of live video from the camera?
There's also an OSS project for iOS/macOS configuration profiles.

I've found a grand total of one good vendor (Mobb) in home health care, with quality and pricing, plus a few original designs, with manufacturing in Taiwan. They may be a positive outlier because they are a subsidiary of a larger business selling medical uniforms.
The challenge seems to be that most products for the elderly are designed for institutional buyers like nursing homes or state/national governments. So you have the usual misaligned incentives when the buyer is not the user (see: enterprise software).

Our research sets out to look at how this system of interconnected smart devices affects our privacy.. and how can we show this with a practical analysis and vulnerability analysis of our own smart devices.
Even though the attack surface of SPA is conspicuously broad and there has been a significant amount of recent research efforts in this area, research has so far focused on a small part of the attack surface.. this is the first.. characterization of the security and privacy issues and countermeasures of SPA.
We conclude that though numerous privacy concerns and security vulnerabilities associated with the device are mitigated, many vulnerabilities still need to be addressed. The aim is not to give you a full date picker, instead only the lower-level building blocks that allow you to build your own. You likely already have your own inputs, buttons, popover etc components. So why not use them?https://www.wayaround.com (custom) and https://gototags.com (generic).
For Amazon Basics WiFi smart plugs, the device type can be configured as "Light" instead of "Plug".
Echo 4 works as a Zigbee hub, avoiding dependency on a third-party cloud service.
